Flood Risk Management Plan

Under the Flood Risk Regulations 2009, Monmouthshire County Council, as the Lead Local Flood Authority (LLFA), are required to produce the Flood Risk Management Plan, which follows on from the Preliminary Flood Risk Assessment and the Local Flood Risk Management Strategy. The draft of the Plan deals with the risks of flooding from surface water run off, rivers, brooks and streams. The Plan includes maps of the flood risk areas for all 33 of the Town and Community Council areas in Monmouthshire and these can be zoomed in to see more detail.

Comments can be emailed to the Council on: flooding@monmouthshire.gov.uk

Responses will be reviewed and the  document amended to take account of those responses as far as is possible. We will also seek to respond to all points raised. The final document will be then be considered by the Cabinet Member for approval before being submitted formally to Welsh Government for their approval. Once Welsh Government has approved the document, with any amendments they require, it will be published on the Council’s web site.

As referred to above this Plan deals with Surface Water flooding and a separate document covering the flood risks from the sea and main rivers has been produced by Natural Resources Wales. It can be reviewed at: https://www.gov.uk/government/publications/severn-river-basin-district-river-basin-management-plan

The Natural Resources Wales web site also has flood maps for all types of flooding and can be viewed at: https://naturalresources.wales/our-evidence-and-reports/maps/flood-risk-map/?lang=en

Flooding in Monmouthshire can be caused by:

  • Prolonged heavy rainfall affecting river levels
  • High tides overtopping riverbanks and defences
  • Blocked culverts
  • Backing up of drains

Whatever the cause, the impact on communities that are directly affected can be far reaching.

We are aware of the problems flooding can cause and we try to ensure that adequate arrangements are in place to receive flood warnings, to monitor local conditions and respond to requests for help from the community.

If your home is at risk of flooding, please view our ‘Does your home get flooded?’ leaflet.

For details of current flood warnings in force visit the Natural Resources Wales web site.

Support before, during and after flooding

Natural Resources Wales has useful information on their website that gives practical advice on preparing for a flood and what to do during and after a flood.

Support from Monmouthshire County Council:

Before flooding, we:

  • Prepare for potential flooding through planning, training and exercises
  • Ensure that a 24 hour response system is in place
  • Monitor vulnerable locations
  • Consult with the community in key flooding prone areas

During flooding, we:

  • Liaise with all agencies/organisations concerned
  • Activate a large workforce to respond to the needs of the community
  • Issue sandbags
  • Advise on practical/hygiene and safety issues relating to properties
  • Offer temporary accommodation to families affected by flooding

After flooding, we:

  • Offer advice on clean-up
  • Help the community recover
  • Clear the highways and affected public land
  • Provide facilities for removal of damaged household property

You can report an issue anonymously, but by registering your details you can track the progress of your report and receive updates as it is processed.

Smartphone Apps to warn of flooding

For example, “Flood Alert” uses live data from Natural Resources Wales to provide real time flood warnings.  This free service will help the public and businesses in responding to potential flooding.

Flood Risk Regulations 2009

Under the Flood Risk Regulations 2009, Monmouthshire County Council, as the Lead Local Flood Authority (LLFA), was required to identify those areas in the county at risk of flooding with significant consequences – Flood Risk Areas. These are areas or clusters of areas above the flood risk threshold with an affected population greater than 5,000 people at risk. This work excluded main rivers such as the River’s Usk, Wye and Monnow and areas affected by the sea which are dealt with by Natural Resources Wales.

No further immediate action is therefore required under the Flood Risk Regulations.

However there are other areas identified as being at flood risk below the threshold and these form the basis of a Preliminary Flood Risk Assessment, developed and supported by the continuing collection of information on local flood events.

A requirement of the Flood Risk Regulations 2009 is that each Lead Local Flood Authority completes a phase 1 review of their cycle 1 Preliminary Flood Risk Assessment Report 2011 and publishes an Addendum to the original report.  This review identified that since 2011 there have been numerous flood events across Monmouthshire but no significant flood events which have affected 5 or more properties.

Flood Risk Management Strategy

The Strategy has now been approved by Cabinet and the Welsh Government Minister and has been finalised.  An LFRMS summary is now available to view along with a summary of the key actions as Appendix A. The full version of the Local Flood Risk Management Strategy is also available.

Comments or reports of flooding incidents are still welcomed at the following email address flooding@monmouthshire.gov.uk
